Application filed September 5, 1924. Serial No. 736,108.

To all whom it may concern.

Be it known that I, CHARLES E. MARKS, :1 citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Supports, ofwhich the following is a specification.

This invention relates generally to supports and has particular relationto trestles or horses of the character commonly used by mechanics, anobject being to provide means whereby the top of a trestle or horse maybe adjusted to a desired height.

Another object of the invention is the provision of means which may beapplied to an ordinary trestle or horse to accomplish the purpose abovestated.

Another object of the invention is the provision of means wherebytheheight of a trestle or horse may be adjusted which is simple inconstruction, may be quickly and easily operated to obtain the requiredadjustment and which when adjusted will remain in position untilpurposely changed.

Another object of the invention is the provision of a device orattachment of the above character which is secured to the trestle insuch manner as to permit of its ready removal so that if desired thetrestle or horse may be used in the ordinary way.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illus- 7 trated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings Figure 1 is an end view of a trestle or horse with theinvention applied.

Figure 2 is aside elevation showing one end of the trestle or horse.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference charac- 7 ter 10 indicates thetop or horizontal beam of the trestle or horse which is supported ateach end by means of legs 11, the upper ends of which are secured to thebeam 10 while the lower ends of these legs are spaced apart by means ofspacing arms 12. The

trestle shown is of the usual construction, be-

ing adapted for plasterers or bricklayers.

The invention as disclosed includes a tubular member or guide 13, one ofwhich is positioned at each end of the beam 10 with its lower endextending through an opening 14 provided in the spacing arm 12.

The upper end of the tubular member 13 has secured thereon one end of anarm 15, the latter being provided with an opening for the passage ofthis end of the tubular member. The arm 15 is substantially L-shaped andits opposite outer end 16 is spaced from and substantially parallel withthe tubular member 13 so that the device may be engaged over the end ofthe beam 10 with the arm upon one side of the beam and the tubularmember upon the opposite side so that the device is clamped upon the endof the beam.,

Slidable within the tubular member 13 is a standard 17 which is providedwith spaced openings 18. The standard 17 is also tubular and provides atits upper end for the reception of an arm 18 which extends from thebottom of a substantially U-shaped member 19. The position of thestandard 17 within the tubular member 13 is adjusted by means of a pinor spike 20 which is adapted to pass through one of the openings 18 inthe standard 17 and'rest upon a collar 21 which is carried at the innerend of the arm 15 and which is secured to the tubular member or guide13.

This construction is duplicated at each end of the trestle or horse andthe U-shaped members 19 are adapted to receive the opposite ends of asupplemental beam 22 which is arranged parallel with the beam 10 andwhich may through the medium just described be vertically adjusted so asto regulate the height of the trestle or horse.

By mounting the U-shaped members in the manner shown and described, thesupplemental beams may be positioned at right angles to as well asparallel with the beams 10. with the use of two or more trestles.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaim.

Having described the invention what is claimed is The combination with atrestle having .supporting legs at each end thereof and a horizontalbeam connecting the tops of the legs, of a vertically disposed tubularmember positioned at each end of the beam,

means connecting the legs and-engaging the lower ends of the tubularmembers, substantially L-shaped arms having openings in one end thereoffor the passage of the tubular members, the opposite ends of said armsbeing spaced from and parallel With the tubular members to receive andengage over the beam, a supplemental beam positioned above the firstmentioned beam and meansengaging the supplemental beam and adjustablypositioned Within the tubular members for adjustably supporting saidsupplemental beam.

In testimony whereof I afiix my signature.

CHARLES E. MARKS.
